10. Testing the Throttle Potentiometer
1. The throttle potentiometer resistance can be measured with an ohmmeter.
2. Unplu
g
the throttle potentiometer at the connector next to it.
g
3. Analog type meters are recommended for this test.
4. Measure the resistance across the red and white wire on the potentiometer assembly. It should
measure approximately 5K (5 thousand ohms).
5. Measure across the black and white wires on the
p
otentiometer, the resistance should be zero
p
ohms with pedal on the riders in the neutral position or speed knob on the ES2832 and CP2832 in
the full counterclockwise position. When the pedal or knob is moved to the full throttle position, in
should be a smooth resistance change without dropping out. It should measure approximately 5K
(5 thousand ohms) in the full position.
